SEEA-Water and IRWS Statistical standards for water information

Transcription

1 SEEA-Water and IRWS Statistical standards for water information United Nations Statistics Division Department of Economic and Social Affairs

2 Outline The International Recommendations for Water Statistics (IRWS) The System of Environmental- Economic Accounts for Water (SEEA-W) The SEEA-Water and IRWS in the context of official statistics 5 th World Water Forum

3 International Recommendations for Water Statistics (IRWS) Tool to develop and strengthen water information system in countries Provides agreed definitions and classifications of water data items classified Uses a hierarchical structure Provides guidance on how to organize the data compilation Shows the link between these data items and: Standard tables of the SEEA-W International water indicators (e.g WWDR)

4 The SEEA-Water System approach to water information Presents stocks and flows of water Links the physical information to the economic accounts Shows water-related expenditures investment in hydraulic infrastructures fees paid by whom costs of collection, purification, distribution and treatment water rights Set of standard tables

5 Water statistics - IRWS Often developed to address individual issues or questions Often not easy to relate to other issues Often not able to be integrated with economic statistics Difficult to be sure all relevant information is included Data items

6 Water accounts SEEA-Water Is a framework for organising data items using a system approach Organise information in terms of stocks and flows Cover the hydrological system and links it to the economy Help to make sense of the entire picture by showing the inter-relationships Data items organised within a frame

7 Water statistics, accounts and audiences Information pyramid Audiences Increasing aggregation of information Macro data Micro data Water indicators Water accounts Water statistics e.g. basic aggregates at the data item level, time series Amount of data e.g. data regarding water resources, water supply and sanitation, or economic activities and water e.g. Decision makers, and the general public, managers analysts and researchers e.g. Managers, analysts and researchers e.g. Researchers and others conducting detailed analytical research

8 Water Accounts

9 The SEEA-Water and IRWS in the context of official statistics Other water statistics Systems frameworks SEEA Energy balances SEEA-W SEEA-E Output frameworks Intermediate frameworks e.g. IRWS e.g. IRES Input frameworks Compilation Material Compilation Material Cross functional frameworks ISIC, CPC, Asset Classification, Class. of Environmental Activities, Class. of Physical Flows etc Data Data Quality Assessment Frameworks Metadata and documentation (e.g. SDMX)

10 SEEA-Water and IRWS international statistical standards SEEA-Water was adopted as an interim international statistical standard by the United Nations Statistical Commission (UNSC) at its 38 th session in March 2007 IRWS was adopted as an international recommendations by the UNSC at its 41 st session in Feb 2010 UNSC recommended their implementation in countries UNSD under the auspices of the UN Committee of Experts on Environmental-Economic Accounting is leading the implementation strategy for the SEEA-Water and IRWS in collaboration with the regional commissions and water institutions (e.g. WWAP, UN Water, SG Advisory Board on Water, etc.)

12 5 th World Water Forum Topic 6.4 Data for all The 5 th World Water Forum agreed: Lack of integrated water data to inform decision making Need not only physical data on quantity but also data on quality and monetary data Need strong legal and institutional arrangements The SEEA-Water offers a coherent and valuable framework to support national data collection and is an important part of the way forward

14 Physical water assets: Standard Table XII physical units EA.131 Surface water EA.1311 Reservoirs EA.1312 Lakes EA.1313 Rivers EA.1314 Snow, Ice and Glaciers EA.132 Groundwater EA.133 Soil water Total Opening Stocks Increases in stocks Returns from the economy Precipitation Inflows from upstream territories from other resources in t territory Decreases in stocks Evaporation Transpiration Precipitation (dew, mist, rain, sleet, hail, snow) Abstraction of which Sustainable use Surface water (rivers, lakes, glaciers) Evaporation/Actual evapotranspiration Outflows to downstream territories to the sea to other resources in the territory Sea/ocean Groundwater (aquifers) Evaporation Soilwater Infiltratio n Other changes in volume Closing Stocks

19 Summary The SEEA-Water and the IRWS are supplementary publications forming the information system for water in the context of official statistics They constitute a tool to develop and organize water information in a coherent system Allow for integrating information from different sources also with economic information Allow for the identification of data gaps and overlaps Provide a useful tool for Integrated Water Resources Management Provide a tool for water monitoring and policy analysis not only in the water context but more broadly
